Hello,
I hope you're doing well, and we apologize for the delayed response and the trouble.
Ensuring the Document Supports Bookmarks:
- Check for Signatures:
- If the PDF is signed, it may restrict editing features, including adding or viewing bookmarks. To bypass this, save the PDF as a Word document, then resave it as a new PDF. This process removes the signature restrictions, allowing bookmark functionality to return.
Updating Adobe Acrobat:
- Check for Updates:
- Please ensure you have the latest version of Acrobat installed on the machine: 24.005.20xxx Optional update, Jan 30, 2025. Check for any pending updates from the Menu > help > check for updates, install the updates, restart the app and the machine, and check. For more information, see this: https://adobe.ly/4hIs8mS.
- Enable Bookmarks in the App: If you have access to the desktop app, you can enable bookmarks there and then sync your changes to the online version. To do this, open the PDF in Adobe Acrobat Pro, go to the top right corner, click on the customize button, select "common tools," and then "add navigation" to see the "add bookmark" option.
I hope this helps.
Thanks,
Anand Sri.
